Application filed October 22',v `1924. Serial No. Z45,261.

To all wlilom t may concern.:

Be it known ,that I, FRANK R. MILLER, a

citizen of the United States of America, re-p siding at Troy, county ofMiami, and State 5 of Ohio, have invented certain new and usefulFoodflreating` Apparatus, of which the following isa full, clear, andexact description. r n

The present invention relates to food 1,0 treating apparatus andparticularly to :ip-

ent invention is to provide such an appara.

` tus having simple means for retaining the roll in position on itssupporting shaft, said means being easily operable to release the rollfor cleaning or replacement.

Another .object is to provide yielding means for pressing the roller toits work, said yielding Ameans cooperating in retaining the roll inposition on theroller shaft.

Other objects and advantagesyof the inventionwill be apparent from thefollowing description taken in connection with thin accompanyingdrawings, in which:

Fig. 1 is a side elevation, partly in section,

of the present invention, parts of the food im treatingmachine beingindicatedto shoe7 the relation of the vpresent invention thereto; Fig. 2is an elevation siinilar'to Fig. i,

the locking plate being raised to its unlock-I ing position and one ofthe rollers removed;

Fig. 3 is a perspective v-iewof the locking plate. Y

Referring to the drawings, 20 designates the food support of themachine, the supportv 4U being herein shown as an apertured platealthough it will be understood that any other suitable forni of supportmay lie employed. The lfood to `be treated is placed upon this foodsupport 20 in position for the rollers to pass over it. Referencecharacter 21 designatesthe driving shaft of the machine' to the lowerend of which is detachably secured a lower section 22 of driving shaftwhich, 'as shown, is provided with an enlargement to form a shoulder 23,.the enlargement being.

or otherwise treating -food.

`vLonfvritudinally slidable upon the lower part of the driving shaft 22is a head 26 carrying transversely disposed roller shafts 27 whichconstitute bearings for the rollers 2S. A laterally extending pin 29.carried by the driving sha-ft 22 engages the downwardly opening slot 30formed in the head 2G thereby transmitting rotary driving `force fromthe shaft 22 to the head and rollers. Pin 29 also limits the downwardmovement of the cad and rollers on the driving shaft 22 and prevents thesame from falling off the shaft 22 when the latter is removed from theniachin`e.

The inner ends of the rollers 28 are nrovided with bosses or extensions35 to which are secured lannular flange rings 36. A locking plate37which is longitudiiiallv slidable upon the driving shaft 22 is providedat its ends with down-turned lips or anges 38 which are adapted tooverlie the annular flanges 36 of the rollers so as to retain therollers lin position on the roller shafts 27. A coiled spring 40interposed between the locking plate 37 and theshoulder 23 on the shaft22 yieldingly holds the locking platey in' its proper position to lockthe .rollers 28 against endwise removal.

A snacer or sleeve 41 A interposed between the loc-king plate V37 andthe head 26 to prevent' the locking plate from being pressed into directcontact with the roller flanges 36, and also tti-transmit the pressureof the spring 40 to the head 2G thereby yieldingly pressing theV headandthe rollers towards the food support 20. Vliile the spacing sleeve 41has been illustrated as separate 'from the head 26 it is apparent thatit is functionally Dart of the head andy i' inav therefore bemade as anintegral partthereof.

In thev normal operation of the machine' the rollers. 28 move over onthrough the foodstuffs on the food' support or plate 20' and areyieldingly pressedv towards the food support by means of the spring 41.This spring also retains the locking plate 37 in position to lock therollers 28 upon the roller shafts 27 as illustrated in Fig. 1.

placement may be accomplished very easily andI quickly by simply raisingthe locking plate as illustrated in Fig. 2, the flanges 36 of therollers being. then disengaged from the lookin plate and the rollersbeing free to slideo the roller shafts 27. 1

'I he removal' of the rollers for cleaning or, re-' While the form ofapparatus herein described constitutes a preferred embodiment of theinvention, it is to be understood that the invention is not limited tothis precise form of apparatus, and thatehan es may be made thereinwithout departing rom the scope of the invention which is defined in theappended claims.

What is claimed is:

1. In an apparatus for treating foodstuffs, a shaft member, a rollermember pivotally supported thereon, and means for retaining the rolleron said shaft, said means comprising an annular flange carried by one ofsaid members and a yielding hook member carried by the other member andadapted to cooperate with said flange.

2. In an apparatus for treating foodstuffs, a shaft, a roller pivotallysupported thereon, and means for retaining the roller on said shaft,said means comprising an annular flange carried by the roller and ayielding hook member connected with the shaft and adapted to hook oversaid flange.

3. In an apparatus fortreating foodstuffs, a shaft, a roller pivotallysupported thereon, and means for retaining the roller on said shaft,said means comprising an annular flange carried by the roller, a lockingplate movablein a. direction transverse to said shaft and adapted tocooperate with said flange to lock the roller on said shaft, andyielding means for holding said, locking plate in looking position.

4. In an apparatus for treating foodstuffs, a shaft, a roller pivotallysupported thereon, and means for retainingthe roller on said shaft, saidmeans comprising an annular flange carried b the roller, a locking platemovable in a irection transverse to said shaft and adapted to cooperatewith said flange to lock the roller on said shaft, yielding means forholding said locking plate in locking position, and stop means forholding said locking plate out of contact withl said annular flange.

5. In an apparatus for treatin foodstuffs, a central support, aplurality o shafts carried thereby and extending laterally therefrom, aroller pivotally supported on each of said shafts, and a commoncentrally disposed means for retaining said rollers against outwardmovement along their shafts. y

6. In an apparatus for treating foodstuffs, a central support, -aplurality of shafts carried thereby and extending laterally therefrom,aroller pivotally supported on each of said shafts, and a common meansfor retaining said rollers on their shafts, said means being yieldableto permit the ready removal of said rollers.l

7. In food treating apparatus having a food support, a rolling devicecomprising a roller adapted to roll over said support, a roller shaftfor pivotally supporting the roller, means for moving the roller oversaid support, and common means for yieldingly pressing the roller toward`the support and for retaining the roller on its supporting shaft. v

8. In food treating apparatus having a food support, a rolling devicecomprising a rotatable drive shaft, a head connected for rotation withsaid shaft and longitudinally slidable thereon, a transverse' rollershaft carried by the head, a roller rrotatably supported upon thetransverse' shaft and adapted to roll over said food'support, yieldingmeans engaging said head for pressing the head and roller towards thefood support, and means interposed between the yielding means and saidhead and adapted to cooperate with the roller. to retain the latter inv'position on the rollershaft.

9. In` food treati g apparatus having a food support, a rolling devicecomprising a rotatable drive shaft having a shoulder thereon, a headconnected for rotation .with said shaft and longitudinally slidablethereon, a transverse roller shaft carried by the head, a rollerrotatably supported upon the transverse shaft and ada ted to roll oversaid food support, a locking plate slidably mounted on the drive shaftand normally in engagement with said head, the locking plate havingmeans thereon for engaging the rollerto retain the latter in position onthe I roller shaft, and spring means interposed between the shoulder onthe drive shaft and the' locking plate. v

In testimony whereof I hereto aiiix my signature.
